So I think this takes the prize for the favorite birthday gift Greyson received. The beloved bubble gun. It's like a double-prop airplane that you dip in the soap and then push the button to make the propellors whirl. I've never seen such a huge cloud of bubbles with so little effort and Greyson was practically giddy.
I absolutely adore this picture because it is totally candid Grey, which is hard to capture.
